Radius to end of arc differs from radius to start?

I am getting a g code error. Radius to end of arc differs from radius to start. What can I do? Is there a setting I can increase. r1=1.3046 r2=1.3039. I am using Cam Export to generate the gcode.

You don't have enough precision in your CAM output. You need to get it to add enough places after the decimal. Here are the recommendations in the EMC2 docs:

Another way to fix this is to set the CAM package to output the radius (R word) instead of incremental offset to arc center (I and J words). (Not all CAM packages have this option.)
